A bibliography of works on meiosis and somatic mitosis 
in the Angiosperms 
MAURICE PICARD 
The accompanying bibliography was prepared, in the first 
instance, for the compiler’s personal use. He publishes it, be- 
lieving that there is need of such a means of reference to the works 
on meiosis and somatic mitosis in the plants already studied, and 
that, by such publication, interest may be aroused in the groups 
hitherto neglected. As far as the writer knows, there is no such 
bibliography in existence at the present time, nor has the plan of 
citing literature on mitosis with reference to the systematic position 
of the plants studied ever been adopted. Inasmuch as the object 
of the bibliography is to provide a working basis for further research 
no attempt has been made to make the citations on the individual 
plants exhaustive. It is believed, however, that from the citations 
given one can obtain references to all the literature. Works 
published before 1880 have not been cited; the citations extend 
to May, 1913. Works on the morphological development of the 
male and female gametophytes have been mentioned only when 
they contain matter of cytological interest. The writer has used 
his own discretion with respect to articles of questionable relevance, 
and also in deciding whether or not incidental references to somatic 
mitosis should be cited. 
The bibliography was compiled chiefly at the libraries of 
Cornell University, Columbia University, and the New York 
Botanical Garden; and my thanks are due to their librarians for 
courtesies shown me. I am also obliged to Professor G. F. At- 
kinson, Professor R. A. Harper, and Dr. A. B. Stout for access 
to some otherwise unobtainable articles, and to Professor G. F. 
Atkinson for examining the manuscript sheets. 
The writer is aware that such a bibliography as here presented 
must be inadequate in many ways, and he hopes that those who 
can will acquaint him with omitted references. 
The nomenclature employed is that of N. L. Britton’s ‘‘ Manual
